COMBINED PENClL AND PENCIL SHARPENING KNIFE.

SPECIFICATION forming part of Letters Patent No. 448,182, dated March 10, 1891.

Application filed July 31, 1890. Serial No. 360,430. (No model.)

To all whom; it may concern.-

Be it known that I, RHODOLPH II. FRANK- LIN,a citizen of the United States, and a resident of Brooklyn, county of Kings, State of New York, have invented new and useful Improvements in a Combined Pencil and Pencil- Sharpening Knife, of which the following is a specification.

My invention consists in an improved construction of wood pencils and a pencil-sharpening-knife attachment for the pencil, whereby I have provided a more feasible and effective pencil-sharpening-knife attachment for wood pencils than such as are now used, as hereinafter fully described, reference being made to the accompanying drawings, in which- Figure 1 is partly a side elevation and partly a longitudinal section of a wood penoil as I make it for the application of myimproved attachment. Fig. 2 is a similar view of the wood pencil and a longitudinal section of the case or handle of the attachment with the pencil-sharpening knife and rubber eraser in side view. Fig. 3 is a side view of the pencil and attachment complete. Fig. 4 is a perspective view of the case or handle and the knife-blade as made of a single piece of sheet-steel; and Fig. 5 is a diagram of the blank piece of sheet-steel, such as is adapted to make the case or handle and knife-blade as in Fig. at.

I make the wood pencil a with a radial groove 1) along it from the upper end a suitable distance for the length of the knifeblade 0 and a suitable depth for the width of the blade, and I provide a knife consisting of said blade canda tubular handle d, adapted to slip on the upper end of the pencil, and also forming a socket or case for the rubber eraser e, inserted in one end. The knifeblade is inserted in the end of said tubular handle or case that slips on the upper end of the pencil, and is so attached at the back edge that its transverse plane is radial to the tube and to the pencil when applied thereto and so as to be received in the radial groove thereof as the sheath for the blade. The

knife-blade may be attached to the tube in any approved way, as by the studs f on the back inserted from the inside of the tube and headed down on the outside, or it may be part of a plate g of sheet-steel, adapted to form the tubular handle (Z, said part being an extension of one edge of said plate part of its length and also an extension of one end, which plate, being bent on the dotted line h so as to assume the radial position when the plate is rolled into the tubular form, thus provides the handle and blade in integral connection of the blade and tube. Thus I am enabled to furnish a practicably-efficient knife attachment, together with a common rubber-eraser attachment, all of which may be sold together with the pencil; but as the knife attachment will outlast many pencils I also propose to make and sell such grooved-wood pencils separately, to supply those having first purchased the complete device, and having the knife attachment remaining require only the grooved pencil, as represented in Fig. 1.

I am aware of the Cook patent, in which there is a knife-blade consisting of an extension of the tubular handle, forming a transversely-curved blade, and I do notclaim such device. My construction is such as to provide a flat blade of the ordinary and better form, and it also provides for effectually sheathing the blade when not in use, While in that case the blade is exposed on the side of the pencil.

I claim 1. The improved knife attachment forpenoils, consisting of the tube adapted for inserting one end portion of a Wood pencil init, and a knife-blade set radially edgewise in and projecting from one end of said tube, with its back in line with one side and its edge in the axial line of said tube, or thereabout, substantially as described.

2. The improved knife attachment for pen oils consistin of the tube ada ted for ina 2: P

serting one end portion of a wood pencil in it, and a knife-blade set radially edgewise in and projecting from one end of said tube, with its back in. line with one side and its edge in the axial line of said tube, or thereabout, in combination with a Wood pencil having a radial groove adapted to receive said blade when applied for sheathing the blade, substantially as described.

In testimony that I claim the foregoing as my invention I have signed my name, in

presence of two Witnesses, this 15th day of Jnly,-1S90.

RHODOLPH IT. FRANKLIN.
